The 840 series of pressure transmitters is specially designed for measuring pressure in explosive atmospheres (safety class, EEx ia IIC T4, Ta=-20°C to +80°C) as part of a larger overall system. It contains an integrated signal amplifier. The 840 series of pressure transmitters can be used in media temperatures up to 85°C. If the pressure transmitter is used in other applications, the safety and accident prevention regulations specific to that application must be followed.

When using the PT as a safety component in accordance with the EC Machine Directive,When using the PT as a safety component in accordance with the EC Machine Directive,

When using the PT as a safety component in accordance with the EC Machine Directive, Annex IIc, the equipment manufacturer must take any necessary precautions to ensure thatAnnex IIc, the equipment manufacturer must take any necessary precautions to ensure that

The operator or owner of the larger overall system is responsible for following the safety and accident prevention regulations that apply to the specific application.

When planning machinery and using the PT, follow the safety and accident prevention regulations that apply to your application, e.g.:

• EN 60204, Electrical equipment in machines.

• EN 292, Machine safety, general design guidelines.

• DIN 57 100 Part 410, Protection against electric shock.

• EN 50 014:1997, General Requirements

• EN 50 020:1994, Intrinsically safe apparatus

• EN50284:1999, Special requirements fro Group II Category 1G

Mounting and electrical connection of the PT must be done by specialists with EMC training, following all applicable regulations, and in

Operate only with an intrinsically safe, EMC compliant power supply with the following specifications when employing the pressure 4-20mA output:

Supply voltage max.40 V DC Current output max. 100 mA Inductivity max. 0 Capacity max. 0.017 µF

For PT’s that are explosion proof Class I, Division 1, Groups A, B, C & D, the power supply rating is 16-40 Vdc.

Do not lay connecting cables in the direct vicinity of cables carrying higher voltage or used to switch inductive or capacitive loads.

** Each flush diaphragm transducer or transmitter is shipped with a DYNASEAL, Dynisco P/N 633014, for the pressure port seal. Recommended torque, for an adequate seal, is 100 in-lbs. Care should be exercised with the low pressure ranges. The flush diaphragm can be inadvertently overloaded with thumb pressure, which can be the equivalent of several hundred psi.
